Sensitive detection of H2O2 based on MWCNTs/Ti3C2 nanocomposite modified electrode

In this work, MWCNTs/Ti3C2 nanocomposites have been synthesized by a convenient method and characterized in terms of structure and properties by SEM, FT-IR, XPS and electrochemical methods. The electrochemical sensor developed by MWCNTs/Ti3C2 nanocomposites has good electrochemical properties. The sensor has good electrocatalytic performance for H2O2 and was used to detect the concentration of H2O2. The sublinear range of detection was 0.05-1080 μM and the detection limit was 0.017 μM (S/N=3). The sensor has strong anti-interference performance, stability and reproducibility, and has shown good performance in real sample detection.
